What are the three parts to physical security standards for various types of Army equipment in the risk level calculated for each piece of equipment?

The three parts to physical security standards for Army equipment generally include access control, surveillance, and physical barriers. Access control involves restricting entry to authorized personnel only, often through ID checks or keycard systems. Surveillance typically entails the use of cameras and monitoring systems to detect unauthorized access or suspicious activity. Physical barriers, such as fences, locks, and secure storage facilities, are designed to protect equipment from theft or damage, with risk levels calculated based on the value and sensitivity of the equipment.
